  Other features and advantages of the present invention will become apparent from the following detailed description of the preferred embodiments, taken in conjunction with the accompanying drawings.

  The present invention aims to provide a woven or knitted article having a pattern, in particular a three-dimensional pattern, which pattern is made from a processed yarn such as a fancy yarn having protrusions or loops without the need for an additional embroidery process. In order to produce a woven or knitted article with a pattern corresponding to the user's design, it should be ensured that textures such as protrusions or loops are made in the proper position of the yarn, so that the texture A pattern that simulates the user's design pattern can be obtained. In general, processing a yarn is controlled by parameters of the yarn making or processing equipment and / or process. As an example, parameters for controlling yarn processing will be described below.

  An example of a fancy yarn 1 is shown in FIG. 1, wherein the yarn includes a loop 10 and a non-loop portion 11. Loops 10 and loopless portions 11 are staggered along the length of the yarn. In FIG. 2, the outline of the normal yarn manufacturing apparatus 4 for processing the fancy yarn 1 is shown. As shown in FIG. 2, the device 4 includes a feeding roller mechanism 41, a twisting mechanism 42, a feeding roller mechanism 43, and a control mechanism 44 in order along the front direction of the yarn 40.

The first portion 401 of the yarn 40 is rough in shape and stretched between the rear roller 411 and the central roller 412, and then the rotational speed between the rear roller 411 and the central roller 412, the central roller 412 and the front roller With the rotational speed between 413 different, it is stretched between the central roller 412 and the front roller 413 so that the first portion 401 is stretched to effect the effect yarn 402 with the required fineness. Form. The core yarn 403 is fed, and at the same time, the yarn 40 reaches the stage of the effect yarn 402, and a composite yarn 404 composed of the core yarn 403 and the effect yarn 402 is formed.

  The twisting mechanism 42 includes a hollow spindle 421 that rotates along an axis, and a binding cone 422 that rotates around the hollow spindle 421. The composite yarn 404 is fed to the hollow spindle 421 together with the binding yarn 420 wound around the binding cone 422. When the binding yarn 420 is wound around the composite yarn 404, a twisting action is generated, and the fancy yarn 405 is manufactured. .

  The delivery roller mechanism 43 includes a pressure roller 431 mounted below the twisting mechanism 42 that delivers the fancy yarn 405 from the hollow spindle 421. The degree of twisting of the fancy yarn 405 can be adjusted by changing the ratio of the rotational speed of the hollow spindle 421 to the rotational speed of the pressure roller 431. The yarn feeding ratio is determined by the ratio of the rotational speed of the front roller 413 to the rotational speed of the pressure roller 431, and is added to the front roller 413 to form a fancy yarn 405 having a desired loop or protruding structure. It can be adjusted by making the rotation speed between the pressure roller 431 different.

  The control mechanism 44 includes a control device 441, a main motor 442 electrically connected to the control device 441, a first servo motor 443, a second servo motor 444, and a third servo that are separately controlled by the control device 441.

It is programmed to control and adjust the output separately and then to control the rotational speed of the hollow spindle 421, the rear roller 411, the central roller 412, the front roller 413, and the pressure roller 431. By adjusting parameters such as draw ratio, yarn feed ratio and degree of twist, the fineness, bulk height and loop size of the fancy yarn so produced can be changed.

  Referring to FIG. 3, a preferred embodiment of a computer-aided method of making a patterned woven or knitted article according to the present invention is shown to include: A step (11) for selecting a woven / knitted sample, a step (12) for storing two-dimensional image data of the woven / knitted sample, a step (13) for selecting a yarn having desired characteristics, and a yarn processing control data are stored. Performing step (14), reading out image data, determining a pattern position in the knitted fabric sample (15), generating line data (16), manufacturing a yarn (17), and patterning Producing a woven or knitted article. The method of the preferred embodiment can be performed by using the computer-aided system shown in FIG.

  As shown in FIG. 4, the computer support system includes a computer display device 20, an image data storage unit 21, a scanning unit 22, a line data generation unit 24, a yarn processing control data storage unit 23, and a yarn manufacturing device 25. And a knitted and knitted fabric production apparatus 26.

  In step (11) of the computer-assisted method, a woven or knitted fabric sample having a two-dimensional shape and a desired pattern is selected for reference to design and fabricate a patterned woven or knitted article. The woven or knitted sample may be an existing woven or newly designed knitted or knitted fabric. The selected knitted and knitted fabric sample is shown in FIG. 5A and includes a rectangular basic processing region (X) and a pattern (Y) formed in the basic processing region (X). obtain.

  In step (12), a set of two-dimensional image data is produced from the woven / knitted fabric sample (A) and stored in the image data storage means 21. As shown in FIG. 6, the image data is converted into an image displayed on the computer display device 20.

  In step (13), a yarn for producing a patterned knitted or knitted article is selected, and a woven or knitted fabric sample (A) is simulated. The selected yarn is a workpiece yarn, which can be changed from one texture to another by changing the parameters for processing the yarn in the yarn manufacturing process. Different processes can be performed along the yarn to form a pattern on the woven or knitted fabric created from the yarn. In this embodiment, the pattern (Y) of the woven / knitted fabric sample (A) is formed by disposing different yarn textures at appropriate positions of the yarn. For example, when the selected yarn is a fancy yarn 1 having a loop 10 and a non-loop portion 11 as shown in FIG. 1, the non-loop portion 11 of the fancy yarn has a basic processing region (X). Define and loop 10 defines a pattern (Y). As described above, the formation of the loop 10 and the non-loop portion 11 is controlled by parameters such as draw ratio, yarn feed ratio, twist, acceleration or deceleration period, and take-up ratio.

  In step (14), after a yarn is selected, yarn processing control data representing parameters for processing the yarn is generated and stored in the yarn processing control data storage means 23. For example, the entire image of the woven / knitted fabric sample (A) shown in FIG. 6 includes a matrix of units defined in both the vertical and horizontal directions. Each unit represents a rectangle. The basic processing region (X) and the pattern (Y) are color-coded in two different colors, such as black for the region (X) and red for the pattern (Y). Therefore, the unit in the basic processing area (X) is black, and the unit in the pattern (Y) is red.

  Referring to FIGS. 7 and 8, the thread processing control data or parameters for red and black units stored in the thread processing control data storage means 23 are displayed on the computer display device 20. Yarn processing control data or parameters for red units are set as follows. The draw ratio is 20, the yarn feed ratio is 2.2, the twist is 350, the acceleration time is 0, the take-up ratio is 3.12, and the rotation direction is positive. According to the yarn processing control data shown in FIG. 7, the loop 10 can be formed in the fancy yarn 1.

  Yarn processing control data or parameters in black units are set as follows. The draw ratio is set to 20, the yarn feeding ratio is set to 1, the twist is set to 350, the acceleration time is set to 0, the take-up ratio is set to 3, and the rotation direction is set to the positive direction. According to the yarn processing control data shown in FIG. 8, the loop-free portion 11 can be formed in the fancy yarn 1.

  Of course, the selected fancy yarn may have more than two textures, for example, three different textures. In this case, the image shown on the computer display device 20 will have three different colors, and the matrix of images will have units specified by the three colors. The three colors represent three different sets of yarn processing control data. Units having the same color have the same yarn processing control data.

  In step (15), the image data is read along a direction corresponding to the direction of the yarn designed for the woven or knitted article, and the position of the pattern (Y) in the image is determined by the scanning means 22 (see FIG. 4). Reference). In step (16), a set of one-dimensional line data is generated from the two-dimensional image data of the woven / knitted fabric sample (A). Referring again to FIG. 6, in the matrix of image data, the matrix unit defined by the points P1 to P2 represents one course. The scanning means 22 scans the units of the first course from left to right, then the units of the second course from right to left, and continues until the 100th course is completed. In other words, the scanning unit 22 sequentially scans the matrix units sequentially. The direction of the scanning line of the scanning means 22 represents the length direction of the yarn, so that the length of each course and the total length of the course included in the matrix can be measured. Line data can thereby be generated.

  For example, the matrix contains 100 × 20 units. 100 units are formed in the longitudinal direction (column direction), and 20 units are formed in the width direction (row direction). If each unit in the width direction has a length of 2 cm, the width of the woven / knitted fabric sample (A) is 40 cm (20 × 2). The length of the yarn required for each course is calculated to be 40 cm × 3 (take-off ratio) = 120 cm. Due to the presence of the pattern (Y), the length of the yarn required in each course from the 20th course to the 80th course is 8 (units) × 2 (unit width) × 3 (retraction ratio) +12 (Unit) × 2 (unit width) × 3.12 (reception ratio) = 122.88 cm. The total length of yarn required throughout the course is the total length of yarn required to produce a woven or knitted article that simulates the woven or knitted sample (A).

  When producing a plurality of woven or knitted articles, the total length of the above-mentioned yarn must be increased so that the yarn has a plurality of processed yarn portions so that each yarn has the above-mentioned total length. These processed yarn portions need to be arranged at intervals, and an extra yarn portion needs to be arranged between them for identification.

  As described above, the color of the basic processing region (X) and the color of the pattern (Y) in the image of the woven / knitted fabric sample (A) are different. When the image is scanned by the scanning unit 22 by making the colors different, the positions of the pattern area (Y) and the basic processing area (X) in the matrix unit are detected and determined. Since the matrix unit is scanned by the scanning unit 22 along the course direction of the matrix representing the length direction of the yarn, the information detected by the scanning unit 22 is composed of line data indicating the interval and length of the yarn. . To form the pattern (Y), the yarn is represented by one texture at the position represented by the matrix unit in the area of the pattern (Y) and by the matrix unit in the basic processing area (X). It is necessary to provide other different textures at other positions. The position of the different texture is represented by position data indicating the distance of the thread from a reference point, for example the starting point of the thread.

  In step (17), the yarn selected as described above is manufactured by the yarn manufacturing apparatus 25 (see FIG. 4) by the control program using the above-described line data and yarn processing control data. Based on the generated line data and yarn processing control data, the yarn manufacturing device 25 can be controlled to change the texture of the yarn 1 at a predetermined position and perform each processing within a predetermined length range. .

  Referring again to FIG. 2, the yarn is produced by the yarn production device 4 with the aid of the controller 441 programmed from the aforementioned yarn processing control data and line data including position data. As shown in FIGS. 7 and 8, the two sets of parameters differ in yarn feed ratio. Specifically, the yarn feeding ratio is 2.2 in FIG. 7 and 1 in FIG. During yarn production, according to these parameters, the controller 441 causes the yarn feed ratio when the yarn 40 fed to the yarn production device 4 reaches the distance indicated by the position data generated from the image data. Is commanded to the yarn manufacturing apparatus 4 to change.

  Referring again to FIG. 6 in combination with FIG. 2, during the manufacture of the fancy yarn 1, the total length of yarn required for the production of the woven or knitted article is obtained by scanning the matrix units from the first course to the 100th course. Thus, after the yarn portion 40 having this full length is fed and processed by the yarn production device 4, additional portions of the yarn 40 equal to this full length are continuously fed into the yarn production device 4. Then, additional portions of the woven or knitted article can be made. In order to distinguish the leading and trailing parts of the yarn, an extra yarn part can be placed between the two parts. This excess yarn portion is discarded after the woven or knitted article is manufactured.

  In step (18), a woven or knitted article with a pattern is manufactured by using the yarn manufactured in step (17) by the woven / knitted fabric manufacturing apparatus 26 (see FIG. 4). As described above, by controlling the processing of the yarn, the finished woven or knitted article has a pattern that simulates the pattern of the woven or knitted fabric sample (A). The knitted and knitted fabric manufacturing apparatus 26 can be a known weaving machine or knitting machine.

  Referring to FIG. 9, as an example, a plurality of yarn processing control data sets and position data for controlling the processing of the yarn in the yarn manufacturing apparatus 4 are provided. These data are programmed to control the yarn manufacturing apparatus 4 to produce another patterned woven or knitted article.

  Referring to FIG. 10, another woven or knitted fabric sample is shown as a gypsy style having a stripe pattern (Y '), a non-stripe portion (X') and a border edge (Z '). Patterned woven or knitted articles simulating this woven or knitted fabric sample can also be produced by the computer-aided method and system of the present invention.
